Doing crafts with your children is an excellent activity to keep them entertained at the same time that you’re improving your bonds. In this article we’ll explain in detail how to make a periscope out of cardboard step by step. A periscope is a great tool for your children to start learning the basics of physics and vision while they have a good time. Children will surely love this item, as they will be able to see things they normally don’t see because of their height. The process to make this periscope with cardboard is really easy and you won't need many materials. Tell your children to help you build the periscope or give them the instructions so they can make it themselves. They will surely enjoy it!

You'll need:

  • A piece of cardboard 42cm long by 42cm wide
  • 2 strips of cardboard about 32cm long and 8cm wide
  • 2 small mirrors about 8cm long and 6cm wide
  • A pencil and ruler
  • Tape and scissors

If you made all three sides of the triangle 8 cm, how could you get 45 degree angle for the mirror attached along the hypotenuse of the triangle?
